• Strobe length: Tso

• Time required for data setup: TDO
Approx. 115 µsec.
TIP 1. Data output timing
• Input signals (F/R, HOLD) will be checked just before starting the data output.
• In the ready state or continuous-run measurement, the result data will be
outputted for each measurement interval. However, if the number of averagings
is set to between 1 and 4 times, the output data may be thinned.
• In the single-run measurement or zero-run measurement data of "0" will be
output. Also during a setup that accompanies measurement such as for calibra-
tion or offset function, data of "0" will be output.
2. While the HOLD signal is on, measured data will not be outputted, if present.
3. Note that meaningless data may be outputted, if the F/R signal is switched in a
single measurement (not a simultaneous measurement).
4. By the F/R signal it is possible to switch between the foreground and background
data during the display is latched. To do this, wait for at least 2 ms from the rise
of the STB signal. It takes about T
D
(maximum 2 ms) from the output of a new
data to the output of the STB signal.
